To wHoM 1i MAY` ooNesRN:

Beit known that I, Pres LEE SHEPLERof Whitehouse, in the countyof.Lucas, and State of Ohio, have invented a new and useful Improvementin sawing-Machines; and I do dee-lare that the following is a true andaccurate description thereof, reference being had to the accompanyingdrawings, and to the letters of reference ,markedthereom and being apart of this specification. l i y Figure 1 is ya. plan view of myapparatus. l e v v Figure 2 is a. perspective view of the method ofcommunicating motion.

Figure 3 is a side elevation of the saw-guide, andfdog, and rest; also,showing drums.

'Ihe same letters indicate like parts in each figure.

The nature of this invention is to adapt any kind of power that may bedesired, to driving circular saws and drag-saws, in such n. mannerthatboth'may be used at the same time,or either separately, as required.

In order to accomplish this end, I construct a suitable freine, A, tosustain the working parts of the apparatus. Upon this frame A is securedthe frame B, upon which runs, in suitable boxes, C, the driving-shaft D,to the outer end of which any desired power may be attached.

E is a bevel-gear, rigidly attached to this shaft, and engages withbevel-gear F, also rigidly attached to shaft G, and gives moti'nthereto. i t

I-I is a gear-wheel, also rigidly attached to the shaft D, and engageswith the pinion-I, and gives motion to the shaft J', which runs insuitable boxes, K, attached to the bearings L, placed upon the frame B.V

The pinion I-is loosely sleeved upon thc shaft J', and should beattached to the band-wheel M, which, in turnyshould be attached to-thehalf of the clutch-N, so that all would form biit one piece in effect,and all loosely sleeved upon the shaft J. V.

The other k half of the clutch, O, is rigidly attached'to the shaft J,at the outer end of' which should be attached the' fly-wheel P. v i A Qis a crotched lever, intended to be used to engage and diseng'age the`two halves, N and O, of'the clutch.

The pitman R is connccted'by a. proper wrist-pin to fly-wheel P, and, atits opposite end, to the cross-head S, which has a reciprocating motionbetween the ways T, supported upon proper bearings.

U is an arm, .one end of which is attached to the cross-head' S, whilethe other is secured to the drag-saw V, which passes between, and isheld in place by the vertical guides W.

X is :L lever, fulcrumcd to vthe vertical guides W, its outer end beingprovided with a dog, Y, which is slotted, so that while assisting tohold the leg being operated upon,.it will also, by means'of thc slot,guide and steady the outer end of the drag-saw.

Z is a rest, pivotcd to the carriage-frame A, and. provided with a slot,B, within .which works the arm of the curved lever C", and by meansrofwhich the end of the logmay be elevated ordcpressed at pleasure.

The shaft G is provided with al sleeve, D", operated in its forward orbackward movement by the lever E,

and forms one-half of a clutch, the other half, F, of which is rigidlysecured to thc shaft G", running in proper boxes, II, upon thecarriage-frame A. Upon this latter shaft is rigidly fastened the spoolI, around which winds the chain or rope J, the other end of which isattached to the carriage K, which is constructed in the usuel manner,andiprovidcd with dogs, L, 'by means of which the log is held in place.

Upon either side ofl the spool I, and upon the same" shaft, arc looselysleeved the drums M, which will revolve independently of'each other,yand upon which the log rests. By means ofthese drums, I am able to drawbaekithe carriage without moving tho log, as, the drums being sleeved,the shaft and spool areallowcd to revolve without giving motion- `to thedrum'. i- 4 By means of a band-wheel, M, and a suitable belt, motion maybe given to a circular saw when desired.

What I claim as inyinvention, and desire to secure by Letters Patent,is- 4 l. Theoombination of the drums l shaft G", spocl I, chain J", andcarriage K, all arranged to operate as herein described and shown. i y

2. The rest Z, when provided with a slot, B", and operated by means ofthe eurvedand bent lever C, all as and for the purpose described andshown. A i
